CMJ0500 TR PBFREE

Overview

The CMJ0500 TR PBFREE is a surface mount silicon current limiting diode manufactured by Central Semiconductor Corp. It belongs to the CMJ series of field effect current regulator diodes designed to maintain constant current over a wide voltage range. The device is housed in an epoxy molded, low profile SOD-123FL case. Key electrical parameters include a peak operating voltage of 100 V and a power dissipation rating of 500 mW. The nominal regulator current (IP) is 0.515 mA, with a minimum dynamic impedance of 2.0 MΩ at VT=25V and a maximum limiting voltage of 1.1 V at IL=0.8 x IP MIN.

Feature Summary

• Maintains constant current over a wide voltage range
• Manufactured in a low profile SOD-123FL epoxy molded case
• High reliability construction

Applications

• Applications requiring constant current regulation
• Biasing circuits for semiconductor devices
• Current source applications

Procurement Notes

Verify the specific ordering suffix against manufacturer documentation to confirm plating options. The PBFREE suffix indicates lead-free compliance. Confirm package type and reel quantity requirements directly with authorized distributors or the manufacturer to ensure alignment with production needs.

Selection Notes

Select this component based on the required nominal regulator current of 0.515 mA and the 100 V peak operating voltage limit. Ensure the application operates within the specified junction temperature range of -65°C to +150°C. Verify that the dynamic impedance characteristics meet the circuit's stability requirements.

Part Context

This part is part of the CMJ0130 through CMJH220 series from Central Semiconductor. The series offers various current selections ranging from 0.13 mA to 22.5 mA in the standard CMJ line. These devices are silicon field effect current regulator diodes intended for surface mount applications.

Replacement Considerations

Direct substitutes should be sought from the same CMJ series with matching current ratings. Cross-referencing requires verifying identical package dimensions (SOD-123FL), voltage ratings, and current tolerance specifications.
